To solve the equation \(-1 + t = -7\) for \(t\), we need to isolate \(t\) on one side of the equation. This can be done by adding 1 to both sides of the equation.
Paso 1: Planteamiento de la ecuación
Comenzamos con la ecuación dada:
\[
-1 + t = -7
\]
Paso 2: Aislar \(t\)
Para aislar \(t\), sumamos 1 a ambos lados de la ecuación:
\[
t = -7 + 1
\]
